Summary: David compares God to a judge but also a defending warrior, asking Him to protect him and keep him safe.
Response: So over the weekend, I took my problem to some people I trust in these matters, and the main consensus is that David is showing his most primal emotions to God. After all, God's definitely big enough. I'm not always that way. My brain will have a primal thought and work it over before saying or writing anything about it. After all, my personality is that of a people pleaser, and it's not very pleasing to get yelled at or point out flaws. I know there is some value to what David is doing and, in my private time, I hope to be more fully human in that way.
